The light output range I provided encompasses both typical highbeams and lowbeams. I've been hit in the eyes many times with highbeams when driving at night and have never been temporarily blinded, nor had my vision temporarily knocked out.

I do agree that a very bright light shined in a dark-adapted person's eyes might buy you a second or two under ideal conditions, but even at close range I think it's an exaggeration to say that person would be temporarily blinded.

I've tested my various bright flashlights (100-850 lumens) in the dark by shining them at myself in a mirror, and while it's obviously unpleasant and does cause some level of visual impairment when trying to look directly at the beam (some pretty nasty, but small, washed out spots in your vision), I've never experienced anything I would equate with being temporarily blinded.
